docstr: Sets the solidity of the pattern fill. Solidity is roughly the
  fraction of the area filled by the pattern. Solidity of 0 shows
  only the background color without pattern and solidty of 1
  shows only the foreground color without pattern.
  
  The 'solidity' property is a number and may be specified as:
    - An int or float in the interval [0, 1]
    - A tuple, list, or one-dimensional numpy array of the above
  
  Returns
  -------
  int|float|numpy.ndarray
